AREAS AFFECTED...NE GA NEWD INTO NC

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 111501Z - 111700Z

IMPRESSIVE 230 METER 12-HR H5 FALLS AT SLIDELL WILL SHIFT ENE TOWARD
THE SERN ATLC CST/SRN APLCNS THIS AFTN/EVE.  1000 MB SFC LOW OVER NE
AL IS EXPECTED TO DEVELOP ALONG THE FOOTHILLS OF THE APLCNS INTO
UPSTATE SC/NC BY 21Z.  ENHANCED SELY LLVL FLOW DOWNSTREAM FROM THIS
FEATURE WILL ADVECT MID-UPR 60S SFC DEW POINTS ACROSS THE PIEDMONT
AND NEARLY TO THE FOOTHILLS BY EARLY AFTN.  STRONGEST INSTABILITY
WILL REMAIN OVER THE LOWLANDS...BUT A FEW HUNDRED J PER KG MUCAPE
WILL EVOLVE WELL INLAND BY MID-AFTN.

THE CONVECTIVE BAND NOW OVER CNTRL GA AND NRN FL WILL LIKELY
MAINTAIN CHARACTER AS THE STRONG HEIGHT FALLS SPREAD ENE.  STRONGEST
TSTMS WILL LIKELY FAVOR THE HIGHER THETA-E AIRMASS FROM THE
FOOTHILLS EWD TO THE CST.  HERE...SELY LLVL FLOW RAPIDLY VEERING AND
INCREASING WITH HEIGHT WILL FAVOR A TORNADO THREAT WITH BOTH
PRE-FRONTAL DISCRETE STORMS AND EMBEDDED ROTATING FEATURES WITHIN
THE LINE.  FARTHER NW ACROSS THE MOUNTAINS...CONVECTION MAY BRING
DOWN HIGHER MOMENTUM AIR TO THE SFC FAVORING DMGG WIND RISKS.

ATTM...EXPECT THAT A TORNADO WATCH WILL BE NEEDED FOR AT LEAST
CNTRL/ERN SC INTO PARTS OF NC.  A SVR TSTM WATCH MAY BE NEEDED
FARTHER W OVER THE MOUNTAINS IN PARTS OF NE GA AND WRN SC/NC.
